CARRYING MECHANISM.

T 0 all whom it may concern Be it known that we, JOHN 1. HUNTER and HENRY KUnN'rzLnR, citizens of the United States, residing at fillies-Barre, in the county of Luzerne and State of Pennsylvania, have invented new and useful Improvements in Carrying Mechanism, of which the following is a specification.

This invention relates to carrying mechanisms for calculating machines, and its novelty consists in the construction and adaptation of the parts as will be hereinafter pointed out.

Figure 1 a side elevation of the frame of the machine supporting a train of mechanism embodying our invention; Fig. 2 is a similar view of the same parts when the main shaft is on its return stroke; Fig. 3 is is av side elevation of themechanism, illustrating the carrying operation; Fig. 1 is a detail of the carrying cam; Fig. 5, of its latch lever; Fig. 6 is a detail of the numeral wheel rib, and Fig. 7 is a detail of the zero restoring position of the carrying cam and numeral wheel.

In the drawings, 1 is the frame of the machine, 2 is the main shaft adapted to oscillate in suitable hearings in the frame 1 and actuated by a manually operated handle (not shown) or in any other suitable manner.

3 is a segment lever mounted on the shaft 2 and provided with a stop foot 4 adapted to engage a fixed part of the frame 1 (not shown).

Mounted on the shaft 2 is a crank 5 (Fig. 2) carrying a roller 6 which travels in aslot 7 of a lever 8, which is secured to its upper end to a rock shaft 9 arranged across the frame of the machine. Arms 10 depend from the shaft 9 and at their lower ends support a restoring rod 11. A transverse shaft '12 supported in suitable bearings in the frame 1 carries elbow levers 13, one for each denominational series, each loosely mounted on the shaft 12, and each yieldingly connected from its upper arm 11 through a draft spring 15 to the restoring rod 11. The lower and rearwardly projecting arm 16 of the elbow 13 cooperates with Specification of Letters Patent.

Application filed June a, 1913. Serial No. 776,104.

'or drive member 17 which extends forwardly in the frame and the movementof which in that direction is limited by stops 32 in the same manner as the rack barsin the former styles of this machine shown and described in Letters Patent of the United States Nos. 715,539 and 797,032, granted to Charles Wales.

Each bar 17 has a depending projection 1S which is adapted to be engagedby the restoring rod 11 and it is also provided with a pin 19 adapted to engage a slot 23 in a segment gear 20 loosely mounted on a cross shaft 21. the gear being constantly under tension of a spring 22 secured at its other end to a fixed point in the machine so that the rear edge of the slot 23 is in constant engagement with the pin 19.

The upper edge of the gear 20 is provided with teeth 2-1 adapted to mesh with the teeth 25 of a pinion 26 secured to or made integral with a numeral wheel 27 on the periphery of which the proper integers are displayed in the usual manner.

It -will be understood that there is one control bar, one segment gear and one nu Ineral wheel for each denominational series.

All of the numeral wheels are loosely mounted to rotate on a common shaft 28 which is supported in suitable bearings and which bearings are adapted to be raised and lowered, in unison with the operation of the parts of the mechanism, by appropriate means indicated at 29 which is not otherwise shown in this application as it forms no part of the present invention.

Fixedly mounted above each numeral wheel is a detent 30 provided with depending teeth 31. adapted to be engaged by the teeth 25 of the numeral wheel pinion when the numeral wheel system is raised.

It will be understood that the key board system adapted to cooperate with the de-,

In Fig. 1, the numeral wheel 27 shown is the units wheel and the segment gear 20 cooperating therewith is the units gear, and is broken away to show the tens segment gear 20 behind it. 10 is the units arm and is broken away to show the tens arm 10 be hind it. 17 is the units control bar and is broken away to show the tens control bar 17 behind it.

Secured to or made integral with each numeral wheel 27 is a cross rib or trip 35 (Fig. 6), the outer tips 350 of which are coincident with the periphery of the wheel.

In the plane of each, of the ribs 35 is a cam 36 (Fig. 4) provided with a vertically arranged upwardly extending member 37 slotted at 38 and 39 to engage cross rods 40 and 41 arranged across the frame 1 and which rods-keep it in vertical adjustment. It is also provided with a sloping cam surface 42, a step shoulder 43 and an edge 44 having a recess45 forming a stop 46 (see Fig. 4). A. spring 47 secured to the cam and to the rod 40 serves to retract the cam to position after actuation. Pivoted to the cam 36 at 48 is a latch lever 49 having a rounded tip 50 (see Fig. at its lower extremity and a slight convexity 51 at its upper extremity to engage the bar 40, against which a spring 52 is adapted to move it.

Mounted to oscillate on the restoring rod 11 and in a plane midway between the planes of the adjacent units and tens numeral wheels, is a carrying elbow lever 53 slotted at 54, to engage a pin 55 projecting from the arm the elbow lever having an upper pin 56 adapted to engage the cam surface 42 of the cam 36 and a lower pin 57 adapted to engage the tens segment gear 20. Undue movement of the lever 53 is prevented by the pin 55. y

The parts of the machine are normally in the positions shown in full line in Fig. 1., the positions of some of the parts at the end of the forward stroke of the main shaft being indicated in dotted outlines. When an item is enumerated 0n the key board, the depressed keys serve to move the corresponding key stops, one of which is indicated at 32, to their effective positions.

The main shaft 2 is then oscillated toward the operator, who stands at the front of the machine. This rocks the crank 5, the roller 6 and, through the latter, the lever 8 which, in turn, rocks the shaft 9 and swings the bar 11 forward. The draft spring thus stretched, oscillates the elbow 13 and advances the control bar 17 until it contacts with the stop 32 and its further forward movement ceases. The further movement of the bar 11, if any takes place, merely stretches the spring 15 without affecting the position of the control bar 17.

Simultaneously with the forward movement of the control bar 17, its pin 19, in

moving forward, has permitted the segment gear to rotate on the shaft 21 under tension of the spring 22, the extent of its movement being governed by that of the control bar 17 and determined by the particular key which has been depressed to set the stop 32.

The main shaft is now at the extreme end of its forward stroke and the crank 5 and lever S are in the positions indicated in dotted outline in Fig. 2. in the meantime, by the appropriate mechanism 29 (above referred to but not described), the numeral shaft 28 has been lowered and all of the numeral wheel pinions 26 are in mesh with their respective segments 20, as shown in Fig. 2, and have been moved out of engagement with their respective detents 30.

On the reverse stroke of the main shaft, the lever 8 is rocked backwardly to press the restoring rod 11 against the edges of the projections 18 on the bars 17, as shown in Fig. 2, to simultaneously move the bars 17 rearwardly. In such movement, the pins 19 cause the segment gears to rotate on the shaft 21 and in so doing, rotate the numeral wheel pinions 26, thus rotating the numeral wheels to accumulate the items set up by the keys, and stretching springs 22 to store them with energy for use during the next accumulating operation.

The detents serve to lock the numeral wheels when the latter are in their normal positions disengaged from the segment gears and the teeth on the segment gears 20 serve a similar purpose when the numeral wheel shaft is lowered, therefore, any tendency of the numeral wheels to over rotate is reduced.

lVhen a new item is enumerated on the key board, the cycle of operations above referred to is repeated, but if the second item enumerated on any wheel brings the sum of two items beyond 9, it is necessary to carry the tens digit to the wheel of next higher order. How this is done will now be described: It will be understood that two series of digits from 1 to 0 through 9 are displayed on the periphery of each numeral wheel.

Assuming that the units numeral wheel has been moved to the 9th position so that if moved one tooth farther it should carry the tens digit to the tens wheel, such units wheel will be in the position shown in Fig. 2. \Vhen this wheel, in the. enumeration of another item, is rotated in the direction indicated by the arrow, the rib will be moved to contact with the shoulder 43 and will move the cam 36 vertically downward (the slots 38 and 39 and bars and 41 serving to guide such movement) until the latch lever 49 has been carried down far enough for its convex surface 41 to be pulled over hy the spring 52 to engage the bar 40 (see Fig. 2) to hold the cam 36 in its lowest position where its surface 42 is in effective ponaaa sei sition to be engaged by the pin 56 of the carrying lever 53*. In other words, the rotation of the units wheel has set the units cam 36 into an operative position, as shown in Fig. 2, and has itself been rotated to indicate the partof the item added in excess of 10.

The carrying lever proper 53 is mounted on the restoring bar 11 and when this bar, in the operation of the machine, during the rearward stroke of the main shaft, is moved sufficiently, as shown in Fig. 3, the pin 56 on the carrying lever is brought into contact with the sloping surface 42 of the cam 36, and, as the lever 53 is itself free to rotate on the bar 11, the continued movement of the bar 11 brings the pin 57 against the segment gear 20 and moves the latter one tooth, the parts being to timed and positioned to accomplish a movement of this extent and no more. In order to insure greater accuracy, however, the slot 23 is made of such length that a further movement of the segment gear is prevented by the pin 19*. There must be a relative movement between the segment gear 20* and the control bar 17 during the carrying operation and the elbow lever 13 must remain idle during such opcitation in order not to actuate the printing mechanism.

Practically simultaneously with the carrying operation, and at the end of the return stroke of the main shaft, the rear edge 100 of the arm 10 strikes the tip 50 of the latch lever 49, to oscillate the latter on its pivot 48 against the tension of the spring 52 and disengage the surface 51 from the bar 40 to allow the cam 36 to move upward to its normal position under the influence of its spring 47.

It sometimes occurs in the usual operation of the machine that the restoring bar 11 is very near to the segment gear 2O when the carrying operation takes place. The slope of the surface 42 in the cam 36 is provided to meet such condition and to insure the proper rotation of the carrying lever 53* even when the pin 56 and surface 42 are practically in contact when the cam 36 begins to move.

When the machine is to be cleared or the numeral wheels restored to zero, the numeral wheel shaft is lowered through the appropriate mechanism provided for that purpose, to cause the numeral wheel pinions to engage with their respective segment gears. How this occurs is immaterial to the present invention, but when it has occurred, and the main shaft is oscillated, the control bars 17 rock the segment gears and cause all of the wheels 27 to be rotated backward. As their respective ribs 35 are rotated, the tips 350 of these ribs are brought underneath and against the stops 46 and their further movement is prevented. This position correwheel and the wheels remain at such sponds nearly to the 0 position of each posi tion even if such forward stroke is not completed, because the further forward oscillation of the bar 11 is accommodated by the stretching of the draft springs 15. At the actual termination of the forward stroke, the numeral wheel shaft is lifted to disengage the pinions 26 from the gears 20 and the wheels are positioned at 0 and are locked in that position by the detents 30.
